Simultaneous speech-to-speech translation (Simul-S2ST, a.k.a streaming speech translation) outputs target speech while receiving streaming speech inputs, which is critical for real-time communication. Beyond accomplishing translation between speech, Simul-S2ST requires a policy to control the model to generate corresponding target speech at the opportune moment within speech inputs, thereby posing a double challenge of translation and policy. In this paper, we propose StreamSpeech, a direct Simul-S2ST model that jointly learns translation and simultaneous policy in a unified framework of multi-task learning. StreamSpeech is an “All in One” seamless streaming model for speech recognition, speech translation and speech synthesis, which can effectively identifies the opportune moment to start translating within the streaming speech inputs. Experiments on CVSS benchmark demonstrate that StreamSpeech achieves state-of-the-art performance in both offline S2ST and Simul-S2ST tasks. Besides, StreamSpeech is able to present high-quality intermediate results (i.e., ASR or translation results) during simultaneous translation process, offering a more comprehensive real-time communication experience.

<h2 class="title is-3 has-text-centered">Introducing StreamSpeech</h2>
<div class="content has-text-justified">
<p>
<strong>StreamSpeech</strong> is an “All in One” seamless model for offline and simultaneous speech recognition, speech translation and speech synthesis.<br>
StreamSpeech employs two-pass architecture that first converts source speech into target text hidden states (autoregressive speech-to-text translation, AR-S2TT) and then generates target speech via non-autoregressive text-to-unit generation. The source/target/unit CTC decoders are introduced to learn alignments via multiple tasks of speech recognition (ASR), non-autoregressive speech-to-text translation (NAR-S2TT) and speech-to-unit translation (S2UT), accordingly guiding StreamSpeech when to start recognizing, translating and synthesizing.
<br>
<br>
🎈<strong>Highlight</strong>:<br>
1. StreamSpeech achieves <font color="red">state-of-the-art performance on both offline and simultaneous speech-to-speech translation</font>.<br>
2. StreamSpeech can perform streaming ASR, simultaneous speech-to-text translation and simultaneous speech-to-speech translation via an <font color="green">"All in One" seamless model</font>.<br>
3. StreamSpeech can present <font color="blue">intermediate results (i.e., ASR or translation results)</font> during simultaneous translation, offering a more comprehensive low-latency communication experience.<br>
